Mexico Mid-Month Core Inflation Rate YoY
A first-half-month measure of annual underlying consumer-price inflation in Mexico.
Full explanation
Mexico’s Mid-Month Core Inflation Rate YoY shows how prices in the core part of the consumer basket have changed from the same half-month one year earlier. It is based on the first-half-month reading of Mexico’s National Consumer Price Index (INPC). Core inflation excludes the items whose prices are considered more volatile or less directly determined by market conditions, making it a measure of underlying consumer-price pressure. INEGI publishes the first-half-month INPC results near the end of the month.
Why traders watch it
Traders watch it because persistent underlying inflation can affect expectations for Banco de México policy, Mexican interest-rate pricing, government-bond yields and MXN sentiment.
Market interpretation
- MXN
- May affect peso sentiment when the result changes expectations for Banco de México policy or Mexican interest-rate differentials.
- Mexican government bonds and interest-rate markets
- May influence pricing of the expected policy-rate path, particularly when it differs materially from consensus.
Stronger vs weaker outcomes
A higher-than-expected annual core reading may be interpreted as evidence of firmer underlying price pressure and may influence expectations for a less accommodative policy outlook. A lower-than-expected reading may be interpreted as softer underlying inflation pressure, subject to the wider inflation, activity and central-bank backdrop.
A higher-than-expected reading may be seen as firmer underlying inflation pressure and may lead participants to reassess the outlook for monetary policy.
A lower-than-expected reading may be seen as softer underlying inflation pressure and may lead participants to reassess the outlook for monetary policy.
Compare the annual core reading with expectations, the prior release and the accompanying headline inflation details.
Typical volatility
High. This is a year-on-year comparison for a half-month period, so base effects and the distinction between core and headline inflation can materially affect the result. The release should be considered alongside the headline, non-core and full-month INPC readings.
Trading considerations
- Expect liquidity and spreads to change around the scheduled release time.
- Compare the result with consensus, the previous first-half-month reading and the headline INPC measure.
- Check services and goods components where available, rather than relying only on the aggregate core rate.
- Consider base effects and any revisions or methodology changes when comparing annual rates.
